Optical Character Recognition (OCR)

Optical Character Recognition is the conversion of images of words to a text file that users can then search and edit. It can be used to create text files from images of handwritten text, scanned documents, pictures that have words appearing somewhere in them, or any other form of non-text document that visually features words.
